Why do you assume falling interest rates? They are still historically low, and what reasons would there be for them to fall back to 1% for 10 years (or similar)?
The market assumes this (= interest rates will fall again in the medium term), as you yourself wrote in your post before. Otherwise, you wouldn’t currently pay more for a fixed interest rate over 10 years than for 5 years. This inverted yield curve usually only exists during recessions or special events like right now. Currently, the ECB is practicing so-called "frontloading," meaning interest rates are being pushed very quickly to the target level. I expect further adjustments by the end of the year. After that, nothing more will happen. The ECB is also aware that this is a supply shock. Furthermore, many Southern European countries would no longer withstand higher yields, which will occur, for more than 1-2 years.
